TROLLEY.

SPECIFICATION forming part of Letters Patent No. 65 5,014, dated J uly 31, 1900. Application filed January 3, 1900. Serial No. 202. (No model.)

To ctZZ whom it may concern: v

Be it known that I, FELIX J. ROGERS, a citizen of the United States of America, residing at Grafton, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Trolleys, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain new and useful improvements in trolleys, and is particularly adapted to be employed in connection with overhead-trolley systems, and has for its object to attain a constant connection between the motor of the car and the overhead or current wire.

In overhead-trolley systems considerable trouble has been experienced in retaining the trolley-wheel in engagement with the overhead or current wire and the consequent breaking or discontinuance of the motive current. I aim to overcome this objection by the provision of an auxiliary trolley-pole upon which a trolley-wheel is mounted, together with novel means of construction which will permit of themovement of said auxiliary trolley-pole, so as to permit thesame to retain the trolley-wheel in engagement with the trolley-wire.

' Briefly described, the invention comprises, in combination with a trolley-'-stand,'which is mounted upon a car, a trolley-pole mounted to swing upon said stand with a spring con nected to the stand and engaging said pole for holding the samenormally elevated, and an auxiliary trolley-pole mounted upon the trolley-pole proper with a tension-spring so arranged as to hold the wheel of the auxiliary trolley-p0le in engagement with the wire, with means connected to the auxiliary trolleypole for limiting the movement imparted thereto by its spring.

The novel features of construction will be hereinafter specifically described and them particularly pointed out in the appended claims,'and in describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, in which- Figure 1 is a side view of myimproved trolley with the pole partly broken away and the stand partially in section. Fig; 2 is a front view of the same. Fig. 3 is a sectional view of the sleeve which is mounted upon the trolley-pole proper for attaching the auxiliary pole thereto. Fig. 4 is a plan view of one of the keepers attached to the trolley-pole proper and to the auxiliarypole forlimiting the movement of the latter.

Referring to the drawings by referencenumerals, 1 indicates asuitable casting which is mounted upon the top of the car and is provided with a peripheral flange 2, which forms a bearing for the revolulole plate 3, upon which the trolley-pole proper is mounted. This plate 3 is held in position upon the trolley-stand by means of an annulus 4, which is bolted or otherwise secured to the flange of the stand and is provided on its inner edge with a groove 5, which is adapted to receive the periphery of the plate 3. This plate 3 is provided on its upper face with a standard or lug 6, upon which the trolley-pole 7 is mounted by securing the lower end of said trolley-pole ina ferrule 8, havingabifurcated or yoked end 9 to engage the sides of the lug or'standard 6 and secured thereto by a journal-bolt 10, which projects outwardly for some distance at each side of the trolley-pole andhas arranged in each of its projecting ends a pair of headed pins 11. The standard or lug 6 is arranged upon the upper face of the plate 3 toward one edge thereof, and adjacent to the opposite edge of the plate is arranged a pair of eyes 12, which are adapted to receive the ends of a substantially U- shaped tension-spring 14, the cross-bar 15 of which connecting the two members of the spring engages the underneath face of the trolley-pole proper and retains the pole normally in an elevated position, the said members of the spring 14 passing overthe projecting ends of the journal-bolt 10 between the pairs of headed pins: 11, and the latter serving to retain the springin position ;The ends of the spring are preferably screw threaded, and the tension may be increased or diminished by adjusting the nuts 16, which are mounted on said screw-threaded ends.

The trolley-pole 7 has mounted thereon at a suitable point a sleeve 17, which may be readily fastened to the trolley-pole 7 by a t r i 685,63

key 18, pressed firmly against the trolley-pole by means of set-screw 19, operating through the under side of said sleeve. On its upper face this sleeve carries a standard or lug 20, to which is pivotally attached an auxiliary trolley-pole 21. has a trolley-wheel 22 mounted on its upper end, with a moving cord or cable 23 connected 'thereto at any suitable point, The trolleywheel is held in constant engagement with the current-wire by means of a substantially U-shaped spring 24, thetwo members of which engage through the eyes 25, provided therefor on the sleeve 17, and have their free ends screw-threaded and held by nuts 26 in. the same manner as a spring, 14 is held on' the trolley-stand. v The cross-bar connecting the two members of this spring 24 engages underneath the auxiliary trolley-pole-21, so. as to hold the wheel carried by the latter in contact with the current-wire. The forward movement which might beimparted to the auxiliary trolley-pole by the spring 21in case the trolley pole was in engagement with the current wire is limited by a yoke or clevis 27, the arms of which pass through the keeper 28, which is shrunk or otherwise secured to the auxiliary trolley-pole a short distance above its pivotal connection with the trolleypole 7 and through a like keeper-'29, which maybe secured in any desirable manner upon the trolley-pole 7 above the point of connec- 7 tion of the auxiliary trolley-pole with trolleypole, 7, said arms being screw-threaded at their free ends and having mounted thereon nuts 30, whichare of a greater size than the eyes of the keepers 29, in order that when they engage said keeper the movement of the a pole 21 will be arrested.

When it is desired to remove the trolleywheel from engagement with the current-wire,

the pull upon the cable or cord 23 will draw the pole 21 downward, compressingthe spring 24 and allowsuch removal, while during the travel of the car the spring 24, assisted by the action of the spring 14 against thetrolley pole 7, will serve to hold the trolley-wheel in engagement with the wireat all times, and, during the passing of the car over switches or the like the'rotary movement of the plate 3'will allow of the trolley-wheel alining and remaining in engagement with the current- 'W1Ie.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1'. In a trolley for electric cars, the combi-; nation, of a plate rotatably mounted in a troll Icy-stand and provided with eyes, a trolleyf pole pivotally secured to said plate, a sub-;

stantially Ll-shaped spring mounted upon This auxiliary trolley-pole the pivotal pin of the trolley-pole with the cross-bar which connects its twomembers engaging the underneath face of the trolley-' pole and its ends adj ustably secured in the eyes on the plate, a sleeve mounted upon said pole andprovided with eyes, an auxiliary trolley-pole pivotally secured to said sleeve with a trolley-wheel mounted on its upper end, a
